Re: Need Advice please: microcontroller with RS-232 Output

Hello Alex,

I've check on the Microchip website for Pic Microcontrollers, there's a lot of product ! How can I choose the microcontroller that will fit my needs?


The usual way. I am currently doing that for two other projects. First, pick a target price limit. Then go through the lists of the major mfgs (TI, Atmel Microchip etc.) and check the specs. Piece by piece. That can take days if you want to really minimize cost and maximize integration (which I usually have to do...). If cost isn't a big deal you can pick a uC that just "has it all".

As Warren wrote, you'll most likely end up with a uC that can do a bit more than you really need. How much more depends on the time you invest reading data sheets and comparing budgetary prices.

Regards, Joerg
